MiniMax-Text-01 is a 456 billion parameter language model developed by MiniMax, a Chinese AI company backed by Tencent. Its killer feature is the 1 million token context window — that's approximately 750,000 words, or roughly 10 full-length novels in a single API call.
For comparison, GPT-4o's context window is 128K tokens (about 96,000 words). MiniMax gives you 8x more context at 25x lower cost.
| Model | Input (per 1M tokens) | Output (per 1M tokens) | Context Window |
|---|---|---|---|
| MiniMax-Text-01 | $0.20 | $1.10 | 1,000K |
| GPT-4o | $5.00 | $15.00 | 128K |
| Claude 3.5 Sonnet | $3.00 | $15.00 | 200K |
| Gemini 1.5 Pro | $3.50 | $10.50 | 1,000K |
Key insight: MiniMax-Text-01 is the only model that combines a 1M context window with sub-dollar pricing. Gemini 1.5 Pro matches the context size but costs 17.5x more.
| Task | Tokens Used | MiniMax Cost | GPT-4o Cost |
|---|---|---|---|
| Analyze a 200-page PDF | ~80K input | $0.016 | $0.40 |
| Review entire codebase | ~500K input | $0.10 | N/A (exceeds limit) |
| Summarize a book | ~300K input | $0.06 | N/A (exceeds limit) |
| Legal contract analysis | ~150K input | $0.03 | $0.75 |
MiniMax API is accessible through NovAI's OpenAI-compatible endpoint. If you already use the OpenAI Python SDK, you're ready to go:
from openai import OpenAI
client = OpenAI(
api_key="nova-your-key-here",
base_url="https://aiapi-pro.com/v1"
)
response = client.chat.completions.create(
model="minimax-text",
messages=[
{"role": "system", "content": "You are a helpful assistant."},
{"role": "user", "content": "Summarize this document: ..."}
],
max_tokens=2000
)
print(response.choices[0].message.content)# Read an entire book/codebase
with open("large_document.txt", "r") as f:
document = f.read() # Can be up to ~750,000 words!
response = client.chat.completions.create(
model="minimax-text",
messages=[
{"role": "system", "content": "Analyze and summarize key points."},
{"role": "user", "content": f"Document:\n{document}\n\nProvide a detailed summary."}
],
max_tokens=4000,
stream=True # Streaming recommended for long responses
)
for chunk in response:
if chunk.choices[0].delta.content:
print(chunk.choices[0].delta.content, end="")| Scenario | Best Choice | Why |
|---|---|---|
| Documents > 128K tokens | MiniMax | Only affordable option for ultra-long context |
| General chatbot | GPT-4o / Qwen | Better conversational quality |
| Code generation | Claude / DeepSeek | Better code quality |
| Chinese content | Qwen-Max | Best Chinese language support |
| Budget-constrained | MiniMax | 25x cheaper than GPT-4o |
| Document Q&A at scale | MiniMax | Process 1000 docs for $16 |

Get Free API KeyMiniMax-Text-01 costs $0.20 per 1M input tokens and $1.10 per 1M output tokens. It offers a 1 million token context window, making it the cheapest ultra-long context model available.
Through NovAI's OpenAI-compatible API gateway, you can access MiniMax models instantly without Chinese phone verification. Just change your base_url to aiapi-pro.com/v1 and use model name minimax-text.
MiniMax-Text-01 supports up to 1 million tokens (approximately 750,000 words) in a single API call. This is 8x larger than GPT-4o's 128K context window.
MiniMax is decent for code review and analysis (especially with its large context window), but for code generation, DeepSeek or Claude typically produce better results. MiniMax's strength is processing massive amounts of text cheaply.
